Surface-conduction electron-emitter display - Wikipedia, the free encyclopedia When the electrons cross electric poles across the thin slit, some are scattered at the receiving pole and are accelerated toward the display surface by a large voltage gradient (tens of kV) between the display panel and the surface conduction electron emitter apparatus. The surface conduction electron emitter emits electrons that excite a phosphor coating on the display panel, the same basic concept found in traditional cathode ray tube (CRT) televisions. The surface conduction electron emitter apparatus consists of a thin slit across which electrons tunnel when excited by moderate voltages (tens of volts). en.wikipedia.org /wiki/SED-tv   (339 words)

Field emission display - Wikipedia, the free encyclopedia A similar technology to be commercialized in 2007 is the SED (surface-conduction electron-emitter) display. Instead of a single electron gun, a field emission display (FED) uses a large array of fine metal tips or carbon nanotubes (which are the most efficient electron emitters known), one positioned behind each phosphor dot, to emit electrons through a process known as field emission. A field emission display (FED) is a type of flat panel display using phosphor coatings as the emissive medium. en.wikipedia.org /wiki/Field_emission_display   (347 words)

ITworld.com - Canon, Toshiba to start SED production this week It's being developed by companies like Seiko Epson Corp. and Samsung Electronics and is also being pushed as a TV display technology, although it has yet to reach commercialization. SED panels can produce pictures that are as bright as CRTs (cathode ray tubes), use up to one-third less power than equivalent size PDPs and don't have the slight time delay sometimes seen with some other flat-panel displays, according to the companies. SED technology has been under development for more than 20 years and is being positioned by Canon and Toshiba as a better option for large-screen TVs than PDP (plasma display panel) technology. www.itworld.com /Comp/3825/050823sed/pfindex.html   (578 words)

Home Cinema News The electron emitters used by SED displays addresses each individual pixel on the panel directly. By contrast, SED has as many electron emitters as there are pixels on the screen. A specific voltage is applied at this gap to accelerate the electrons, which are emitted through a vacuum and ultimately collide with a glass plate coated with two layers of phosphor (the actual screen). www.homecinemachoice.com /cgi-bin/shownews.php?id=8328   (720 words)

HDBlog.net » SED/NED SED (Surface conduction Electron emitter Displays) is that great new flat-panel technology that promises a flat plasma-like form factor and a great CRT-like image. Instead of having one gun to shoot all those electrons, a SED display has an electron emitter for each pixel. SED displays promise to be thin like LCD and plasma, but to have a picture quality like CRT. www.hdblog.net /index.php/category/hdtv-displays/sedned   (2192 words)

Technology watch, SED - Surface-Conduction Electron-Emitter Display: Home Theater Blog Home Theater News & Reviews The inner workings of SED borrow from both LCD and Plasma technologies; a glass plate is embedded with electron emitters, one for each pixel on the display. Sure we now have flat panels that can display resolutions of up to 1920x1080 pixels or higher in rare instances, but the often shunned CRT technology is capable of resolutions of 2560x1920 and higher, well within the future-proof 1080p spec. The emitters on this plate face a fluorescent coating on a second plate. www.hometheaterblog.com /hometheater/2005/05/technology_watc.html   (407 words)

PCWorld.com - Toshiba Eyes Alternative Flat TV Technology Toshiba plans to launch a television based on a new flat-panel display technology called SED (Surface-conduction Electron-emitter Display) in 2005, a company executive says. SED is one of several emerging display technologies that, according to their respective backers, do a better job than either LCD or PDP.

SBF Glossary: E to ECUSA The initially incident electrons, called primary electrons, can reëmerge from the solid surface with a large fraction of their initial energy; such electrons are called backscattered electrons (BSE). Electronic band alignment at semiconductor heterointerfaces are determined from the electron affinities of the two semiconductors. In those interactions, the energy gained by electrons in the solid is often sufficient to ionize them; the electrons thus ionized are called secondary electrons (SE). www.plexoft.com /SBF/E.html   (7202 words)

Define surface-conduction electron-emitter display - a definition from Whatis.com - see also: SED The surface-conduction electron-emitter display (SED) is a flat-panel, high-resolution display currently under development by Canon and Toshiba. The SED consists of an array of electron emitters and a layer of phosphor, separated by a small space from which all the air has been evacuated. Prototype electron emitters have been developed with diameters of a few nanometers (billionths of a meter). searchwinit.techtarget.com /sDefinition/0,,sid1_gci797765,00.html   (275 words)

EETimes.com - Venture cuts its own path to flat TV panels The SED panel basically has a CRT-like structure but replaces the electron gun with electron emitters, said Shunichi Uzawa, newly named president of SED Inc. The electron emitter has a plane structure and an emitting area that consists of an ultrafine palladium oxide (PdO) particle film layer, electrode layer and glass substrate. A prototype SED display provides color reproduction, viewing angle and video response equal to a CRT, the companies said, but it achieves a contrast in dim light of 86,00:1, said to be nearly three times higher than the best dim contrast of PDPs. In addition, the SED display's emission efficiency of over 5 lumens/watt is much higher than the 1 to 2 lumens/W of PDPs. www.eetimes.com /showArticle.jhtml?articleID=47900163   (1289 words)

Flat screens exploit electron emission technology - ZDNet UK News But rather than using one gun that fires electrons in a single stream, SED uses a second glass plate mounted with electron emitters -- several for each pixel. When a small voltage is applied across this gap, electrons are released from the emitters. SED is a technology that holds the promise of very high picture quality while using less power than alternative displays such as plasma screens. news.zdnet.co.uk /0,39020330,39166657,00.htm   (446 words)

Sound And Vision Magazine: SED: A New Player in the Flat-Panel Game In an SED, on the other hand, the electronics are mostly digital but the display itself is analog: a pixel glows continuously with an intensity directly proportional to the strength of the electron beams hitting its color phosphors. Since an SED is a panel, with a total panel thickness of less than 8 millimeters in the prototype that was on exhibit, the electrons don't have to travel very far. SED is the name of a display technology being developed by Canon and Toshiba. www.soundandvisionmag.com /article.asp?section_id=7&article_id=1203   (510 words)

A Super-Duper Surface-Conduction Electron-Emitter Display - New York Times SED (surface-conduction electron-emitter display) works a lot like a traditional tube TV, in that an electron gun fires at a phosphor coating on the glass; that is, you get all the picture quality of CRT. But an SED set has one electron gun for EVERY SINGLE PIXEL, which means that the screen can be very thin, like a plasma. Today I finally saw a demonstration of SED, a new flat-panel TV technology (jointly developed by Canon and Toshiba) that's supposed to blow away plasma, L.C.D and even tube televisions. www.nytimes.com /2006/01/06/technology/poguesposts/06pogue-SED1.html?ex=1294203600&en=b98e7d565438b2a2&ei=5088&partner=rssnyt&emc=rss   (233 words)

HDBlog.net » Blog Archive » He Said She SED It’s called SED which stands for “surface-conduction electron-emitter display”. Well, an SED is much like a CRT except that where the CRT had one (or three) guns at the back of the display shooting electrons at the phosphorous screen, an SED has “guns” called “electron-emitters” for every pixel. SED displays have all the display-quality advantages of CRT, and the convenience advantages of LCD and plasma. www.hdblog.net /2005/03/21/he-said-she-sed   (250 words)

Move over LCD, SED is on the way - GameDev.Net Discussion Forums Each subpixel has its own tiny low voltage electron emitter right behind it, instead of being scanned by a magnetically-guided high voltage electron beam from afar, as with a CRT. A prototype SED display was apparently showcased with a contrast ratio of a whopping 100,000:1. SED displays will be able to display our games with all the rich contrast of a CRT, along with support for insanely high resolutions, and games are one area where you can always do with a higher resolution. www.gamedev.net /community/forums/topic.asp?topic_id=344513   (2703 words)

Canon to roll out new flat screen technology - Jan. 25, 2006 SED displays operate on the same principle as cathode-ray television, emitting light by shooting electrons into a phosphor-coated screen.

First Toshiba SED TVs to have 50-inch diagonals ! SEDs, on the other hand, have as many electron emitters as there are pixels on the screen. Since there is no need to scatter the electron beams, it is possible to make far bigger SED displays than would have been conceivable using CRT technology. Light is provided by electrons colliding with the phosphor-coated screen. www.cdrinfo.com /Forum/printable.asp?m=117888   (500 words)

theTechSage : SED Technology for Large Displays on the Horizon Two exciting news items concerning the (near)future of SED display technology: 1) According to EE Times, Toshiba will announce in October product plans in which it will set a product line using their proprietary surface-conduction electron-emitter display (SED) technology - co-developed with Canon - as their flagship line for large displays. As I see it, the real elegance of the SED solution is that it uses the exact same display technique in a flat panel that we know and love in a CRT: excited phosphorous. Currently ANI is in advanced development for the application of electron emitting carbon nanotubes cathodes in a number of areas, including large area color televisions, new lighting devices, x-ray, and microwave generators. thetechsage.com /archive/2004/09/02/217.aspx   (2953 words)

Today @ PC World - Canon Plans HDTV Flat-Screen Displays Using as many electron emitters as there are pixels on the screen, SED technology can create HDTV video quality with all the benefits of a CRT display without the hulking CRT size. Just as CRT technology is based on the targeted emission of electrons from the back of a long vacuum tube against a phosphor-based fluorescent layer in a glass surface, so does SED. The reason sed will be a hit is that it is only as thick as a plasma but has the same picture quality as a tube based tv and will be able to get larger then crts of present. blogs.pcworld.com /staffblog/archives/000905.html   (1242 words)

Toshiba unveils new flat-panel SED TV - Tech News & Reviews - MSNBC.com The new TV uses SED — surface-conduction electron-emitter display — which uses beam-emitting technology similar to the old-style cathode-ray tube televisions, and delivers similar clear imagery but onto a flat panel.

Fractal Neurodyamics and Quantum Chaos/2 Sentience is the capacity of the emitter to utilize the confirmation waves of contingent absorbers in wave-packet reduction, while free-will or intent is the uniqueness implied by the principle of choice. Such time-reversal is used in the transactional interpretation of quantum mechanics (Cramer 1986) fig 14(c), a mutual encounter between emitter and absorber is modelled by the release of crossed-phase advanced and retarded waves, each having zero-energy, the offer wave of the emitter and the confirmation wave of the absorber. Although other unstable systems such as the weather may also display such features of non-locality, it is difficult to think of a physical experiment which could in any way match the brain as a detector of correlations within the stochastic model of quantum mechanics. www.dhushara.com /book/paps/consc/brcons2.htm   (8731 words)

CES 2005 in Retrospect Toshiba was showing off a new display technology known as surface-conduction electron emitter display (SED).
